Serial No. 396,539.

This invention relates to improvements in in furnaces of any type which is designed for.

burning low pressure fuel gas. 1 Another object of the invention is to provide a low pressure fuel gas burner for fur- 1o naces with improved means for supporting the burner in the furnace whereby the same may be swung out throughthe door of the furnace when the doorris opened to facilitate the thorough cleaning out of the furnace fire box. r 7

Still another object of theinvention is to provide a gas burner structure. for furnaces or the like whereby air may be supplied to the burnerin such a manner that the efficient consumption of the fuel will take place with a minimum soot formation. and without the creation of noise during operation. 7

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part-of this specification, with the understandmg;

however, that the invention is not confinedv to any strict conformitywith the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure from the salient features ofthe invention as expressed in theappended claims. i

In the drawings i Figure 1 is aview in front elevation of a furnace door constructed in accordance with the present invention showing the draft con{ trol doors associated therewith; f

Figure .2 is a horizontal sectional view taken upon theline 22 of Figure 1.

Figure 8 is a vertical sectional View taken upon the line 3-3 of Figure 1.

Figure 4 is a face VlGW' of the gas burner 145 plate, a portion of which is broken away to show. the gas manifold therebehind.

Referring more particularly to the drawings wherein likenumerals of reference indicate corresponding parts throughout the 5 several viewsythe numeral "l-indicates generally the front wall of a furnace fire box, portions of the sidewalls thereof being indicated by the numerals 2.

, The front wall 1 is provided with the door opening 3 and at each side. of this opening there extends inwardlyfrom the wall a shield wing 4:.

Mounted upon the lugs 5 projecting from the face of the front wall of the furnace, by means of the-hinge leaves 6, is a door 7, the leaves 6 being secured to the face thereof in the manner shown in Figure 1. This door is of a size to completelycover the opening 3 and has formed transversely therethrough in the central portion thereof the relatively Wide slot 8 which is normally covered by a pair of supplemental doors each hinged as indicated at 10 adjacent opposite side edges of the main door 7 so that they may be: brought intoaligned position against the face of the maindoor to close the slot 8.

-When' the supplemental doors 9 are in closed position theirv free edges are in opposed relation as shown. Each of the supplemental doors 9 has a semi-circular recess 11 formed in the free edge thereof and when these recesses are brought into opposed positionupon closing the doors a circular opening is formed through which a fuel supply pipe may be extended as will be hereinafter described.

Secured to the inner face of the door 7 adjacent the topthereof is a pair of transversely spaced hingehooks 12 and directly beneath each of these hingehooks12' there is secured tothe door a lower hinge hook 13'. i i

' To each of the hinge hooks 12' and 13 is pivotally attached, one end of a burnersup porting arm 14, the hinge shown being effected by forming the arms 14 with suitable apertures through which the hooks may be extended.

furnace door when the burner is in operative position.

At the top and at the bottom of the shell there is attached a pair of hanger hooks, the pair in the top being indicated by the numerals 18 and the pair at the bottom by the numerals 19. As shown the hooks at the top of the burner shell are directed upwardly while those at the bottom are directed downwardly and each of the hooks of each pair has pivotal engagement in an inner end of one of the supporting arms 14 as is clearly shown in Figure 3.

The forward wall of the burner shell is provided with a plurality of relatively closely spaced apertures 20 and within the shell in relatively close proximity to the rear face of the wall 16 is a. gas distributing manifold indicated generally by the numeral 21. This manifold as shown in Figure 4 is of rectangular design and may be provided with a single transverse central portion 22 connecting opposite ones of the side sections 23. This central section of the manifold has con.- nected therewith and opening thereinto a fuel gas feed pipe 24 which extends through the aperture formed between the opposed edges of the supplemental doors 9 to the exterior of the furnace where it is connected by a removable coupling 25 with a feed pipe 26, the feed pipe being provided with a suitable valve 27 to cut off the flow of gas when disconnection of the coupling 25 is necessary.

The wall of each of the sections 22 and 23 of the gas manifold immediately adjacent the wall 16 of the burner are provided with discharge apertures 28 each of which is positioned to eject gas directly through an aperture 20 in the wall 16.

From the foregoing description it will be seen that the burner structure 15 is so supported that when the door 7 is in closed position it will be located in the proper position within the furnace. hen a cleaning out of the furnace is necessary the entire burner structure may be removed with the swinging open of the door 7, the only preliminary operation necessary being the disconnection of the feed pipe 2% with the supply pipe 26 at the coupling25 and the swinging open of the supplemental doors 9. lVhen the main door 7 is swung back the necessary angular adjustment of the burner supporting arms 1% may be made to draw the burner through the furnace door opening 3.

In operation gas is fed into the manifold 21 and ejected through the apertures 28 through the adjacent apertures 20 of the. shell wall 16, this passage of the gas drawing into the apertures 20 about the sides thereof sulfieient air to form a completely combustible mixture. The supply of air to the burner is regulated by the doors 9 and the flow of air through the opening 8 controlled by these doors is directed to the burnerby the wings 4 so that it will pass into the shell 15 and through the apertures 20 in the manner described. Some additional. air will pass through the apertured plate 16 at points Where a supply of gas is not provided, this air mixing with the gas inside the fire box and assisting in its combustion.

From the foregoing description it will be readily appreciated that there has been devised a new, novel and simple type of burner, which may be easily and inexpensively constructed, easily installed and readily shifted from operative to inoperative or vice versa as necessary.

Having thus described our invention, what we claim is 1. In a furnace structure, a fire chamber having a door opening, a door hingedly mounted before said opening, a fuel burner, supporting arms each hingedly attached to the inner face of the door and having hinge connection with said burner, means for conducting fuel to the burner through the door, said door having an air inlet opening therethrough, and draft control doors hingedly connected to the first mentioned door for closing said opening.

2.
